Light Following Robot

Arduino Based Light Following Robot with LDR Sensor

Harsh Sehgal 0 Comments

In this tutorial, we are going to make a light-chasing robot that moves toward areas of bright light. We will be using photoresistors to determine the brightness of the light. For a better understanding, have a look at the line following robot, surveillance robot car, obstacle-avoiding robot that we previously created. A photoresistor, or photocell, is a light-dependent resistor...
